To all rwhom t may concern: y

Be it known that I, JOSEPH T. BOND, a citizen of the United States, and resident of Baltimore, State of Maryland, have invented certain new and useful Improvements in Heads for Spinning Paper and the like, of which the following is a specifh cation.

This invention relates to certain improvements in spinning or crimping heads for use in machinery for making paper receptacles; and the objects and nature of the invention will be readily understood by those skilledy in the art in the light of the following explanation of the accompanying drawings illustrating, what I now believe to be the preferred embodiment or mechanical expression of my invention from among other forms, constructions and arrangements within the spirit and scope thereof. n

An object of the invention is to provide certain improvements in heads for rolling or spinning down the ends of paper walls in the manufacture of paper receptacles and .covers therefor whereby such heads are provided with readily removable and insertible paper engaging bits or elements that can be easily adjusted toward the work.

A further object ofthe invention is to provide a head for spinning down the ends of the'c'ylinders or other walls of paper or like material receptacles in the formation of closures for said receptacles,lwherein the o paper. spinning or working elements are formed by the ends of a series of pins arranged approximately parallel with the longitudinal axis of thehead.

A further object of the invention is to provide a head for spinning the ends of receptacles and cover walls composedA of paper or like material, with spinning or paper engaging bits or elements so constructed and arranged as to ren/der said bits individually removable, insertible, and adjustable.

A further objectof the invention 1s to provide a head for spinning paper walls and the like with improved paper engaging and Working bits or elements that are individually adjustable to take up wear, and

Vthat have their ends formed to operate on the paper\walls in spinningthe same.

A further object of the invention is to provide certain improvements .in construcland close the end tion and arrangementy for the production of a highly advantageous and eiiicient head for spinning the ends of the walls of paper material receptacles and their covers.

The invention consists in certain novel features in construction and in combinations arrangements as more fully and particularly set forth ,and specified hereinafter.

Referring to the accompanying drawings: Figure l, is a side elevation of a portion of a machine for making paper receptacles and covers therefor, which includes the spinning head of my invention. Fig. 2, is a detail plan of the underl or working face of the spinning head illustrated.- Fig. 3, is a detail vertical section in the plane of the line 8-3, Fig.l 2. Fig. 4, is a vertical section in the plane of the line 4.*4, Fig. 2, dotted lines indicating a portion of paper' wall. being 4spundown thereby. Fig. 5, is a detail perspective of. one of the paper working bits or pins carried by said head. Figs. 6 aiid 7, arev detail sectional views of portions of paper inclosing'walls and end closures having end closure locking beads different in vertical thickness.

In the embodiment illustrated by the accompanying drawings, I provide a mandrel over which the paper wall to be spun ,is slipped, while the upper end of thismandrel ,forms a platen or anvil on which iS placed the paper or other diskthat is to of the paper wall. y This mandrel is .supported and controlled by any suitable means lwhich 'form no part of my present invention.

I show a cylindrical paper wall a, surrounding the mandrel and projecting upwardly therefrom a distance above the horizontal plane of the end face or anvil thereof, and snugly fitting within the projecting end of this wall and resting on said anvil or uppeiz', endof the mandrel, I show a paper -Any suitable means can be provided to hold the wall against rotation on the mandrel during the spinning roperation hereinafter described, butsuch means constitute no part of my present invention and I have not fully illustrated the same. V

In the example illustrated, I provide a rotary and vertically movable spinning head above and alined with the mandrel, and

adapted to move down to the paper wallv with said sleeve.

vprojecting upwardly therefrom. and by a spinning action to roll and turn the upper end of the wall inwardly and downwardly and tightly onto said disk and thereby form a joint, roll or shoulder c, within the end of the vpaper wall and confining the disk against movement therefrom. However, my

present invention is not limited to the vertical movement of the head, nor in fact to` the rotation of the head, as any other suitable mechanisms can be provided to cause relative rotary movement between the head and paper wall, and relative movement of other without requiring that the head itself rotate and without requiring that the head itself move toward and from the paper wall.` However, in the example illustrated, a rotary vertically-movable spinning head 6, is provided, and this head issecured to the 'lower'end of av vertically movable rotary sleeve 7, that is raised and lowered by 'a suitably operated swingable arm or fork 8. This sleeve is rotated by and is vertically movable on the lower end of a rotary shaft 9, provided with suitable driving means` such 'as pulley 10. This shaft is mounted in and depends from a suitable support 11, lby which it is held against vertical movement v The spinning head 6, comprises a metal block or disk having a 'central lthreaded bore by which ythe head is'screwed onto or otherwise secured to the lower end of the sleeve 7, concentric with'the shaft 9, which is vinalinement with the longitudinal axis of the paper wall on the mandrel.l This head 6, is formedwith an exterior annular dependin lip or ange 6a, having an internal cylindrical surface vwhose diameter is slightly greater than. theexternal diameter of the projecting upper end of the paper wall to be spun, while the under side or face of said head is formed with an annular or circular vertical groove or socket 6b, at the base of said'flange and whose' outer vertical head and it contains paper spinning bits orelements to start thewall onits inward and downward curl and to then force the samen down-to complete the bead or seam c. These bits consist of a plurality of similar straight elongated steel or other suitable metal pins 61e, arranged longitudinally of the head and extending therethrough and projecting down into said groove vor socket through the roof thereof and uniformly spaced apart around' the circle of the groove. The lower ends of the bits preferablyl all project a uniform disltance into' the groove and below its roof to the wall and head toward and from each form the desired series of paper-depressing elements, and the lower extremity 6f,of each bit is preferably diametrically concaved or grooved at an inclinationl or bevel so as to present a concaved beveled end surface to the paper wall in the direction of rotation of the head. e

The head is formed with a series of preferably uniformly spaced longitudinal holes or perforations opening through the top face of the head and through the roof of the groove 6b, to receive said bits-6e. Each bit fits snugly in'its hole yetrso as to permit lon 'tudinal adjustment thereof. A

eans are yprovided whereby the bits can be independently adjusted, 'can be independently removed from and reinstated in the headfand canbe normally locked rigidly in operative positionY in the desired adjustment. As an example of 'means that can be vprovided for this purpose, I show set or clamping screws 6g, arranged radially of the head and projecting from and operative at the exterior of the periphery of the head and extending through tappedholes: in the head tervals.

into operative engagement with the bits, one

set screw being providedV for each bit. The radialtapped holes for the screws intersect the holes for the bits between the top face of the head and the roof of the groove, and hence each screw can be adjustedv to engage and rigidly clamp and lock its bit posi.-

jtion, or can be as readily adjusted from engagement with'itsbit to permit longitudinal adjustment or removal of the bit controlled thereb As the working ends of the bits are su ject to excessive wear, I preferably employ elongated straight bits of greater length than the head so that each bit can be repeatedly adjusted longitudinally to take upl wear, whereby'each bit can be subjected to most extended or long life-of Servicebefore it becomes so short that it must be discarded fora new full length bit. This feature of ready removal and adjustment is also of peculiar advantage because'of 'the necessity of grinding and re-shapingthe working ends of the bits at more or less frequent in/ In the operation of the device, the paper Wall a, (whetherit be a full length body for a paper receptacle, or a 'shortI` length body orl wall for a slip cover for a receptacle) is fitted on the mandrel and clamped or otherwise held thereto and the paper end or bottom b, is dropped into the projecting end of the wall and onto the mandrel end. The rotary spinning head is then ,forced down onto the projecting end of the paper wall.

The paper wall enters the fiange 63,-- and passes up into the groove and the edge of the wall strikes the outer edge portions of the concaved beveled ends of the bits which start said edge of the wall on its initial inward curve across said concave ends and inwardly across the groove and the opposite edge portions of said concave ends then engage said inwardly moving edgeof the paper wall and turn the same down and hence start said wall on its downward movement. The constantly advancing downward pressure of the head and the rapid revolution thereof cause the beveled concaved bits to quickly crush, compress and curl the paper wall downwardly against the edge of the ring 69, the end thereof along the surface of the paper' disk b, and toward the vertical portion of the paper wall immediately above the plane of said disk. The working ends of the bits completely occupy thepwidth of the groove or socket above .the horizontal plane of the ring 6, and form a series of beveled shoulders that act on the paper wall to quickly produce the tight roll or seam desired with a smooth finish and of attractive appearance and without breaking or mutilating the paper.

The radial width of the roll or seam c, is controlled or determined by the exterior di-l ameter of the ring 6c, while the vertical Width of said seam above the disk b, can also be' controlled by the vertical thickness of said ring. The ring 6c, is hence preferably removably secured to the head for easy removal where unduly worn to permit substitution of a perfect ring and also to ermit substitution of a ring of slightly di erent diameter where a roll or seam of differ.- ent radial width is to be produced, and also for substitution of a ring ofldierent vertical thickness where a roll or seam of dii'erentvertical width is to be produced.

It .will be noted that, as the rapidly rotating head approaches the disk b, in the operation of spinning down the paper wall,

the ring 6, moves down with said head andv as the operation is completed, said ring bears down on said disk and limits the movement of the head toward the disk.

It is evident that various changes, modifications, variations, and1 departures might be resorted to without departing from the spirit and scope of my invention and hence I do not wish to limit the invention to the disclosures hereof.
